The main idea is that self-organization can regulate public transportation systems in such a way that passengers wait less than the theoretical optimum. Of course, this means that the theory was wrong. Well, more precisely, theory made misguided assumptions. I thank Christian Bettstetter and Wifried Elmenreich for organizing the Research Days and Chrisitan Philipp for making the video. Tip: The video is high quality, so it takes some time to download, even if one chooses right click -> Switch to low quality. Cultivate patience...
